The field experiment of Brassica chinensis showed that 7.5 t·hm-2 organic fertilizer with kitchen waste as raw material increased the yield of Brassica chinensis,but it did not reach the significant level;Soil organic matter content was significantly increased by 15.6%,soil bulk density decreased by 0.12 g·m-3,and field moisture capacity increased by 2.7 percentage points.When applying 30 t·hm-2 of organic fertilizer from kitchen waste,it had negative effect on the growth and survival of Brassica chinensis,and the safe application amount of organic fertilizer from kitchen waste should be less than 22.5 t·hm-2.
